Industrial acid pickling and phosphating wastewater mainly comes from the pretreatment or intermediate treatment in industries such as steel, chemicals, dyes, and electroplating. Acid pickling refers to a method of cleaning metal surfaces by using acid solutions to remove oxide scales and rust from metals like steel. Therefore, the pollutants in this type of industrial wastewater are complex, leading to water eutrophication. In the process of treating industrial wastewater from metal surfaces, acid pickling and phosphating wastewater treatment processes are quite common. As a metal protection process, it has certain anti-corrosion and anti-oxidation properties and is also a technique for metal coatings. The treatment of acid pickling and phosphating wastewater has significant value. After the metal undergoes the acid pickling and phosphating process, corresponding wastewater will inevitably be generated, which contains a large number of harmful ions, is low in acidity, and can easily cause certain harm to the environment.
